ATN TICO 6 640x512

Clip-on640-class

The ATN TICO 6 640x512 is a 640×512, 12 µm thermal clip-on behind a 50 mm lens. On the Johnson yardstick that is an estimated 1,042 m detection and 260 m recognition range for a standing person; ATN quotes 3,500 m detection. It is the cheapest of the 10 clip-ons here, at ~$2,995.

how much further the box reaches than a 2-pixel, 0.5 m criterion

One pixel of this unit sees 0.240 mrad (12 µm ÷ 50 mm). Two pixels across a 0.5 m human is 0.5 ÷ (2 × 0.240) × 1000 = 1,042 m. The box figure is usually computed against a person’s 1.8 m height instead, which is why it comes out higher. Full explanation.

What the spec sheet says

Read from the published specifications and this catalog’s own numbers — not from owner reports, which we have not collected for this unit.

For it
  • 640×512 core — 3.0× the pixels of a 384-class unit
  • 12 µm pitch — the 50 mm lens sees what a 17 µm core would need 71 mm to match
  • Published NETD of ≤18 mK, 8th-lowest of the 51 units here that publish one
  • Runs on 18650 cells you can swap in the field
  • 8 h published run time, 21st-longest of 64 here
  • IP67 sealed — survives immersion, not just rain
  • Records video and streams to a phone over Wi-Fi
Against it
  • Detection claim is 3.4× our Johnson estimate (3,500 m vs 1,042 m)
  • 19.9 oz hanging in front of the day scope's objective
